DHSPI systems are portable laser-interferometry instruments that allow for real-time, full-field acquisition of structural condition information of an object in-situ. They are developed to cover a wide range of applications including the diagnosis, evaluation and monitoring of hidden defects inside the bulk of the objects, the assessment of the objects’ condition due to their transportation or to their exposure to environmental changes, the monitoring of conservation interventions, as well as, to verify their originality. The risk priority maps which are the outputs of DHSPI analysis are a unique source of information for the conservator in order to make decisions and plan conservation strategies.
